FLASH LIGHT.

Application filed March 22, 1920.

7 10 JZ whom it may concern Be it known that l, Fran; EvAN-s, a citizenof the United States, residing yin the city ot Summit, in the county oiUnion and-State of ew Jersey, have invented certain new and usefulimprovements in Flash Lights, of which the 'foilowiug is a tull, clear,and exact description.

My present invention relates to improvements in pocket flash-lamps andit consists in the details of construction and in the arrangement andcombination ot parts herein described and claimed.

rlhe paramount object of my invention is to provide mechanism whereby,through the reciprocating movement ot a push-rod, to impart continuousmovement to the train of speed multiplying gears required for theactuation ot' the current generator.

Jfurther object ot my invention is to provide certain Jfeatures ofimprovement in the manner of making contact with the lamp terminal.

Other objects and advantages will appear in the following specification,and my invention is illustrated in the accompanying drawing forming partot' this application, in which Y Fig. l is an elevational view of myimproved iiash-lamp with the front casing section removed. showing thearrangement ot the interior parts.

Fig. 2 is a central longitudinal sectional view.

Fig. 3 is a horizontal cross-section, taken on line 3-3'of Fig. 1. l

1n carrying out the present invention, I prefer to employ an elongatedcasing having rounded ends, the same being made up of complementarysections, cast from iron aluminum, or other suitable material. Thus, inthe accompanying drawing, 4 represents the elongated section for thefront of the casing, being cast with rounded ends 5 and 6, and with aside flange 7 all around. 8 represents the elongated rear section,similarly cast with rounded ends and with a side flange 9 all around.Centrally of the rounded end 5, the meeting flanges 7 and 9 are eachcast with one-half of the circular opening 10. The meeting edges of theflanges 7 and 9 are cast or otherwise made with overlapping tongues 11,which are provided with suitable threaded openings for bottom of thebore Serial No. 367,926.

the reception ot screws as 12, whereby the an axial socket 14, in whichis screw threaded the base of an incandescent lamp 15. This reflectorcarries lens 1G formed on its outer side with al convex surface whichprojects through the opening 10 as shown, and which is designed tointensify the rays of light. Below the reflector socket 14, the plate 8is cast with a projection 17 having a forked end for the reception ot aspool-shaped element 18, consisting oi' nonconducting material; theopposing flanges 19 ot this element engaging over the top and bottomfaces of the forked end, as best shown in F ig. 1. The vertical body ofthe element 18 is provided with abore 20 in which is seated a tubularpin 21, formed with a head designed to engage a terminal of the lampbase. Coiled around this pin is a spring 22, which is 4confined betweenthe and the head of the pin, so as to urge the pin into tight engagementwith the lamp terminal. l

F or supportng the remainder of the working parts, I provide a plate 23,which extends upwardly from the flange 7 alongside the front plate 4,centrally'thereof, and which is connected with the rear plate 8 by thearbors 24, 25 and 26, arranged in parallelism as shown'. Extendingacross the casing and through suitable openings provided in the iange 9is a push-rod 27 whose intermediate portion consists of the rackbars 28and 29. The rack-bar 28 extends above the arbor 24 and has its toothededge in engagement with a pinion 3() loose on said arbor; while therack-bar 29 crosses below thev arbor 24 and has its toothed edge inengagement with a pinion 31 also loose on said arbor. Both pinions 30and 3l have ratchet teeth cut in their faces. Fast on the arbor 24,adjacent the pinion 30, is a collar 32 in which is set a pin 33 normallyurged by a spring 34, into engagement with the ratchet teeth or itspinion. In like manner another collar 35 having a spring urged pin 36,is provided for the pinion 3l.

When, under this construction, the pushrod 27 is thrust to the right,the pinion 30 is turned to the right, while the pinion 31 sof is turnedto the left; and, conversely, when the said push-rod is thrust to theleft, the pinion 30 is turned to the left, While'the pinion 31 is turnedto the right. Now, during the turning of the pinion 30 to the right, thearbor 24 is turned in a similar direction because of 'theengagement ofthe pin 33 with the ratchet teeth of this pinion; and in this instancethe pin 36 is not active on its pinion since it yields from the teeth4thereof. On the other hand, during the movement of the pinion 31 to theright, the arbor 24 is turned to the right because of the engagement ofthe pin 36 with the ratchet teeth of its pinion; and in this instance,the pin 33 is not effective since it yields over the ratchet teeth ofits pinion.

either to the right or tothe left, the arbor 24 is turned to the right.At each end of the intermediate rack-bars, a spring 36 is coiled aboutthe push-rod 27, the purpose being to re-position the latterautomatically after each thrust, Whether made to the right or the left.

Fast on the arbor 24 is a gear Whee1-37 with Which is connected a pinion"38, in mesh with a gear Wheel 39, fast- Witli a pinion 40 on the arbor2 5. The gear Wheel 39 meshes with a pinion 41, fast With a ratchetWheel 42 on the arbor 26. Loosely mounted on the arbor 26 isapermanentmagnet 43, formed With branches 44, between Whichare a seriesof armatures 45, coil wound-in series, and attached to a guard sleeve46, Which is made solid with the rear plate 8. Pivoted at 47 to a branchof the magnet is a pawl 48, which is held inengagement With the teeth ofthe ratchet Wheel by means of a spring 49, pinned at 50 to a magnetbranch. Through this train of speed multiplying gears,y the continuousmovement of the arbor 24 is utilized to cause the magnet 43 to spinaround the armature coils and set up a' current. One end 51 01E-theWinding leads to a In other words, under the thrust of the push-rod 27,

binding postA 52,' Which is screw-threaded-- into the spool-shapedinsulation 18, in position to enga e the interior of the pin 20, and yso conduct t ecurrent to the lamp terminal.

The other end 53 of the Winding is grounded on the casing at 54,- towhich pointthe return from the lamp is effected through the llamp base,the reflector and the casing.

The push-rod 27 may be conveniently actuated by the thumb of the hand inwhich the Hash-lamp is carried; and from the foregoing description,taken in connection with the accompanying drawing, it will be un#derstood that a continuous flash may be obtainedby actuating thepush-rod repeatedly in quick succession. v

y Having 'thus described my invention, what I claim is The combinationof a casing consisting of complementary sections provided with anopening, of a reflector 'and an incandescent lamp supported in saidopening, one of said sections being provided with supportingmeans,Contact making means for said lamp'- removably located on, saidsupporting means, a gear train supported in saidcasing including anarbor, of a pair of pinioiis loosely mountedA on the' arbor and having yratchet teeth cut in their faces, a collarv for f each with `a pinion,whereby upon' movement of the push-rod in either direction the arborwill be moved only in one direction,
